Padres designate Volquez for assignment

The 30-year-old right-hander is 9-10 with a 6.01 ERA in 27 starts this season. He has struck out 116 and walked 69 in 142 1/3 innings. On Friday, he gave up six runs in two-thirds of an inning against the Cubs.

Volquez is 53-50 with a 4.77 ERA in nine seasons with Texas, Cincinnati and San Diego. The Padres originally acquired him as part of the December 2011 trade that sent Mat Latos to the Reds and landed Yasmani Grandal and Yonder Alonso in San Diego.

The Padres recalled 27-year-old right-hander Brad Brach from Triple-A Tucson to fill the roster spot. He is beginning his fourth stint with the Padres this season. Overall, in three seasons with the Padres, he is 3-6 with a 3.92 ERA. In 30 relief outings for Tucson this year, he was 3-3 with three saves and posted an ERA of 2.83.
